The perimeter of a rectangle is 400 feet and the width is 80 feet. what is the length of the rectangle?

The length of the rectangle is 120 feet.

Step-by-step explanation:

The perimeter of a rectangle can be found using the formula:  P = 2W + 2L, where P = perimeter, W = width and L = length.  Since we know the value of two of the three variables, we can plug them into the equation and solve for the missing value ('L'):  400 = 2(80) + 2L or 400 = 160 + 2L. Using inverse (opposite) operations to isolate the variable, we get:  400 - 160 = 160 - 160 + 2L or 240 = 2L.  We then divide both sides of the equation by 2 to get rid of the coefficient:  240/2 = 2L/2 or 120 = L.  So, the length of the rectangle is 120 feet.  

19.

step-by-step explanation:

you add the 9 in the tens column since it is a single digit and 9 plus zero is 9 so it is 19
